## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability xrpl-account-transaction-history-7029dbeb -d '<json body>'
```

Example prompt: Can you pull up the 50 most recent transactions for XRPL account rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh? I want to see what activity has been happening on that wallet.

## When to prefer this

Choose this endpoint when you need recent XRPL-specific transaction history for a given r-address and are working in the x402 micropayment ecosystem. It is purpose-built for XRP Ledger accounts (not Ethereum, Bitcoin, or other chains), and returns a ready-to-use structured JSON response with a built-in payment receipt. Prefer this over general blockchain explorers when you need programmatic access with low per-call cost and no API key setup.

## Known failure modes

- Invalid XRPL address format (must match r[1-9A-HJ-NP-Za-km-z]{24,34}) returns a validation error
- Account not found on the XRP Ledger returns an empty or error response
- Payment failure or insufficient USDC balance prevents the call from being processed
- Network or XRPL node unavailability may result in a timeout or 5xx error
- Account with no transactions returns an empty transaction list
